Writing new XDoclet tags

VECNA Technologies : What We Do contains all the information necessary to write taghandlers and subtaks. I can do most of what I want using the standard templates method. The biggest problem is that using the standard template tags I can not see a way to create a simple comma-delimited list of all the properties defined in my forms.

The cleanest way to achieve this is obviously writing some taghandlers, what is what I am now doing. This link seems to tell me exactly how to do this, so I am off to write it.
